It's sad that a person so well-educated can interpret some post-comatose, revisionist "memories" as something metaphysical or otherworldly. At best, this was a vivid dream and you've no proof otherwise.
Reminds me of Timothy Leary and other such "psychonauts." The only difference here is that the good doctor has replaced hallucinogenics with a traumatized cerebral cortex.
But hey, if you're willing to trade your credibility as a man grounded in medical science, empirical knowledge, etc., why not cash in, right?
